Excellent read. Thanks for sharing.
A good "Tommy" Pinball can be purchased for anything between $1400 and $2200 so u are in luck. Quite a few have been imported into Australia. There are apx 3 or 4 playfield versions. (search Tommy on the forum here and u will see various playfield photos)
Star Trek Next Gen is also a great game. Getting a little pricey now. U can find a real good one between $3000 and $4500 depending on condition. A lot of collectors are hanging on to them. One comes up for sale every now n then.
Good luck with finding your next pin. We all look forward to seeing your collection grow. Welcome to the forum.
