If you had $500 to spend, how would you spend it?

I own an older but great SOTA Sapphire table that I bought used with an FT-3 arm; I added a Benz MC-20 cartridge. It works and sounds great but I'd like to know if it can be improved. Problem is I only have $500 to spend. I'm looking for advice on how to best spend it. Here are some of my options, as I see them:
1) I live close enought to Chicago that I can drive up with my turntable and have SOTA inspect and adjust the machine ($225)
2) On the phone, Donna from SOTA thinks the first thing I should upgrade is arm board ($250)
3) Her other suggestion is to replace the existing felt mat on platter with acrylic mat(?)
4) I guess I could trade in the MC-20 cartridge for a better Benz cartridge
5) Sell FT-3 and buy better arm (?)
6) None of the above. Apply the $500 towards a vacation with the wife.
I'm looking especially to those of you who are/were SOTA owners to advise me how to best spend my $500.
Thanks in advance
