home made: how many tapes? recorded lps to tape? recorded live broadcasts? copied friend's music?
what size reels, tape width, number of tracks, forward and/or reverse format, speed are the tapes?
pre-recorded: I assume there must also be some factory made, same questions ....?
shedding: what brand tape did he use? home made tapes might be the brands that eventually shed, the emulsion comes off the plastic strip, so do some research about that, which brands there is a way to bake tapes that shed
I love tape, it is my best sounding format, however mine is not awesome like my friend's 2 track 15 ips pro model/content
and the content is old, limited playI went thru several machines and settled on Teac, x1000r and x2000r, their last Pro-Sumer decks.
here's one in your budget you might ask more questions about, take a chance on
https://www.ebay.com/itm/306045178137?mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5338381866&toolid=10001&customid=38edd0f8-f9c5-11ef-ae90-636665636265
it plays 10" reels, it plays 1/4" wide tape; it plays 4 tracks (not 2 track stereo), consumer speeds 3-3/4 ips and 7-1/2 ips (does not play 15 ips),
you might consider finding someone who can play a random sample of them, see what they sound like, IOW there is a chance it was fun but they don't sound outstanding, or they are awesome, but so what, it is content you might never want to hear more than once.
IF they are 15 ips and awesome, you will need far more than $1,000, again, verify they sound awesome before spending a lot of money.
