The forums here are pretty awesome and you can get heaps of advice and help for starting your collection.

I started a couple of years ago.. i thought i was starting late

If you want, i have MP12-T Tiger Track i want to sell for $120 transformed once and in perfect cond.

Also if you find something on ebay that seems really really cheap, it's most likely a knock off. Knock Offs (or KO) are bad.. stay away!

have fun on the forums!!
