But you can always get a Shadow or CFTBL and sell it down the road for roughly what you paid and then get a GB. This plan wouldn't work as well if you start with GB.
I agree. They will be making GB for a while and picking one up down the road won't be difficult. Both TS and CFTBL are great pins that you shouldn't lose money on. Buy either, play the heck out of it and then sell/trade it for GB later on. CFTBL will give you longer ball times, but TS is a flow machine when you are "on". Can't go wrong with either.
