I would buy one that is cheap in a heart beat. The problem is most are like $40, so I'd rather just buy a plain one for $15. Maybe if you could find a cheaper (but still quality pad) you could sell them cheaper but still make a profit.
I wonder if you buy, say 50 pads you could get a discount, like buying in bulk? May be something to look into.
A neat idea is that you could sell packages of say a saddle pad, half pad, and polos that are all color coordinated and personalized ;)
Let me know what you end up making, I am interested in a pad or 1/2 pad :)
