Both the 99 and the 15 are good machines. BTW there is also a 3/4 Japanese 15 out there... I have one. I like the 99s you got an ok deal if you found a cool table for yours. The tables aren't easy to find that fit those machines - it might be worth the money just for that. I gave my DGD a Spartan with a needle guard - she loves it. The 15s are nice for free motion work.
