A USED drive for for 144 EUR (if I find one at this price) or a brand new Plexor DL BD-W for ~110 EUR (with many years of warranty - other brands are even cheaper)...I can buy quality DL BD-discs for about 4.5 EUR/disc, or even less.
Well, the drive I have is used, but the software reports that it still has 99% of head life remaining. Those things are built differently - they are enterprise-grade.
4.5EUR * 4 (since a tape holds 200GB) = 18EUR, which is in the middle of a tape price. However, since tapes hold more data, they are more convenient at least for me - less swapping and they take up less physical space while still having a label on the edge. Also, a tape is rewritable, so if I mess something up or find a better version of the TV show or whatever, I can reuse the same tape.
"Brand new" things are overrated. I bought a brand new VCR from a store and it broke after about 1.5 years (and replacing the mechanical part would be really difficult). I am still using a SVHS VCR made in 1994 that I bought on ebay (so I could edit out commercials). One capacitor in it went bad, but replacing it was easy (and cheap - the capacitor was something like 0.1EUR).
Where I live, old LTO-stuff are incredibly expensive (the hungarian average income per month is roughly 250-300 EUR (!), while 1 kgs of bread costs 0,75-1 EUR, 1 l milk costs 0,6-1 EUR and 1 l of gasoline costs ~1,3 EUR...),
In Lithuania, the average income is around 300EUR (which is a bit inflated, since there are a lot of people who get the minimum salary of 231EUR before taxes) and gasoline costs 1.3-1.4EUR/L.
not to mention the new ones; they're FAR out of the average mortal's financial range. If I buy something from e-bay, it's a gamble (as I don't examine personally what I'm buying) and I need a credit card (which I don't have). Besides, there's the shipping cost too (another 10-20-30 EUR)...
the 114EUR was with the shipping cost. I never consider shipping as separate from the price. To me, it's the same if the item costs 1EUR and the shipping is 99EUR or the item costs 100EUR and the shipping is free. In both cases I pay 100EUR.
As for the card - I have a "virtual" one, it can only be used online and it's a debit card. It is useful since I can sometimes get things cheaper on the internet than locally (and sometimes I can only get it on ebay and not locally). This is not limited to data tapes. I can't even get TDK SA audio cassettes locally and have to buy them on ebay.
But I agree - a new LTO drive costs a lot.
Big deal. I'm gonna rewrite my backups in every 5 years for the sake of safety. The price of the BD-media will be ~1 EUR/disc or something like that. Not to mention that I'll be able to use any BD-player (which will be as common as DVD-players nowadays) to playback my files.
I dislike having to rewrite the archive. I want it to be like my audio tape and record collection. I do not re-record my tapes every few years (I have one reel-to-reel tape that was recorded in 1951 - still sounds OK - I bought it on ebay

). Also, this is one of the reasons why I prefer recording music to audio tapes and cassettes. Also, when I record stuff from TV, I use VHS. It's more convenient and reliable for me and I will be able to store the tape for a long time and still be able to play it as long as I have a working VCR. And replacing a VCR is easier than re-recording lots of tapes/discs.
