Welcome to the forum bgdrr1,
It sounds like you did alright for your first machine. The belt and a few bearings is no big deal. Call Buffalo Bearings and they will get you the right bearings. You want them with an r3 code for the triple seals. Tires and wheels are the biggest cost, so if you are good there, everything else takes relatively little money, just some good old elbow grease. Post pics in the gallery when you get a chance too.
