easy coast online wetsuit rental??

I am doing the IronGirl in Syracuse next Sunday.  Based on some recommendations here and elsewhere I bought a sleeveless neosport Jane on ebay.  I actually got two sizes since the race is so close and I fell somewhere in between or at the top end of a 10.  Well, the 10 was HUGE!  At least 3 extra inches of rubber all along the zipper line down my back, and at least a handful behind each knee.  I am not sure why it was so big, as like I said I was at the top end or above the range.  Now I am freaking because I waited so long.  In all reality I can probably do the swim without a wetsuit as the water temps will likely be low 70's.  I just think I would be more comfortable with one.  I am trying to get ahold of the company and see if they think an 8 will work and if they can ship out one today.  All of the local rental places are sold out as there are several tris that weekend.  I am wondering if there are any other online rental places other than wetsuitrental dot com that people recommend.  I may go with them since they seem the cheapest, but they are all the way on the west coast.  Any suggestions?
