bt tm-15. Mini in a milsim body 20bps. new they are around 450 so 300 used should be doable. Few on ebay for around that right now. Empire has all the parts for it and I would take one over a tippman any day. They shoot really nice are very stable and have cocker threaded barrels (tons of options there). They only other options in a milsim style that fit your criteria are a bob long mtac or a dye dam, and they are much much pricier.
Autocockers are not more accurate, I'm just more accurate when I shoot autocockers.
