There's some good bang for the buck pins in the DE/SEGA lineup. I have/had JP, Royal Rumble & LW3 (simple & fast).
I recently played tamoore's SEGA's, Baywatch, BF & ST, and wouldn't mind owning any of them. They're entertaining and most can be had for around $2k or less.
One thing to keep in mind on the DE pins, expect some board repairs/replacement, at least that's been my experience. Can't vouch for SEGA, haven't owned any yet.
