totally agree, as newbie here, recently I bought 708A, 712A and 716A : all of them are with dead laser in different stages, i.e. 708A and 712A the laser is completely dead (it cannot read neither CD, nor DVD, actually 712A was able only once to read one particular CD, but obviously the laser is very very weak) and 716A cannot read CDs, still good for DVDs (but that's more or less useless).
However, at least for 708A and 712A there are replacement lasers available from China - in 1 month or so I will be be able to give feedback and tell if the replacement laser is as good as original, i.e. if they can read my favorite test CDs - those with Cactus protection, i.e. many C1/C2 errors pressed at factory.
So, bottom line, I wouldn't recommend buying 716A at all - as there are no replacement lasers for them. Currently, BW-16D1HT beats PX755/760 in most cases, because of the aforementioned in previous posts firmware bug. So, I guess, only safe bet are 708A and 712A, but if you're willing to replace the laser plus for me it is still an open question if the replacement laser is as good as the original. I ordered mine, but shipping from China takes forever...
Also, Plextor PX-5224 I bought has a fault:

luckily I found way to workaround its fault, but not how to fix it. So, at least for me, so far it turned it's kind of impossible to find second hand Plextor that in 2021 is actually still in fully working order.
