Paxton Novi 1000 - 1 belt or 2

I own a 1 belt Novi 1000 but have not installed it as yet. Paxton says that I can upgrade it to a 2 belt setup. I haven't talked to the sales department to find out how much this will cost.

For those of you in the know would this be a worth while upgrade?

If Paxton's price is out of this world, is there any where else where I could pick up the parts to do the conversion?

Thanks

Mike
