I looked at the stainless steel competition from two other companies (ST and CS) and the 3.5 looks like a bargain to me. The ST 1460 is $995.00 without a PID plus shipping. Deduct the cost of the lesser PID ($199.99) from the 3.5 and the SI is a paltry $5.00 more. Shipping is free, 2 extra shelves, more door latches, and 4 locking wheels. That to me is a bargain. For the CS Amerique/066 at $1899.00. Deduct the cost of it's controller ($718.75) and you are left with a cost of $1180.25, plus shipping. I think Steve has the 3.5 priced just right and it will appeal to a certain segment of the smoking public.
