i've used the fap-69 for a long time now, it is my favorite mid-range fap. the fap-50 i don't find as good in my opinion based on use of both...the 4 extra heal, and faster reload is very noticeable which helps it stand out. it's helpful for fapping through a trox dom and with a little bit of luck i can handle an alpha. a 2350 is also a good backup fap for those quick fap situations. price tag on them currently is a tad bit high, since there is only a couple of people making them, and it costs like 24 peds per attempt, if you can find them for +150 or less, it's worth the investment
only reason for the higher price tag on the 69'er is rarity. tt+350-450 would be a fair price range...
