OK, honest answer given you must stays and 100k hard limit
TOM 6k
Tna get the butter cab cause you can 7k
Afm buy a HEP restore 12k (remakes are junk in comparison and if these are your faves then get the best)
MM buy a HEP restore 12k (remakes are junk in comparison and if these are your faves then get the best)
Restored Classic Bally 81' (whatever one you like but get a nice one; I suggest Centaur as the best for your situation) lets say 7k
Williams IJ > great theme and you need a widebody 7k
TWDpro (the prem just does not shoot as well) 5k
TZ or TAF; you need a lawlor classic and these are the best of his classics 7k
One nice restored EM; I suggest Wizard or 300' or Fireball or 4millBC. Get a good player that is also a 4 person. Lets say 4k cause you want a nice one
Dialed In LE cause it is just fricking amazing. 8k
You need a Sys11 game. Most will say ES or Wwind but a guy like you needs something rare that other people rarely have. You need something that pinheads will be excited to play because they dont see ti often. Get a Transporter. 3.5k
Last one to round out the 12 will be TBL which apparently go for 21.5k now so that takes care of your cash. Cool theme, average game, but rare and pinheads will want to play it.
This collection gets you some diversity, will appeal to you wife, you, casuals that come play, pinheads that come play, and keeps it fresh.
Be prepared as after playing these games for 6 months you can plan on selling half and buying classics from 78-90 era if you want the best in challenge and fun.
You are also going to want to save some money for Danesi #2
