yes, certainly...
microgaming network (gnuf,dream,doylesroom,cd,pokerhost,betway...) offeres Sit & Go's, for a funny rediculous buy-in price, for as many as 0.09 cents!
So: a dollar will cover the buy-in for minimum 11 sitango tables
.
poker.com offeres an MTT game for only 0.06 cents - about 250 ppl there, so first prize would be 3$.
Juts make sure that the site you choose to invest you money in- to start yout microgaming voyage, is comfortable for you to play in...
Scrawnybob has a good article here somwhere about "choosing the best site for you".
have a look in it as well
Cheers
and good luck!
