Why are there SO many Pronto's for sale?

Do people buy 'em and then not fully use them?
Do people find out that they hate touchscreen remotes?
Do people simply want to upgrade to the ProntoPro?
Is it just that because these are so expensive that people feel compeled to try to salvage their investment when they do not bond with the remote, .vs. shelving a $30 remote?
Are these just way overpriced and not worth the $$$.

Not to be critical of the pronto, it's just that every time I go to Marketplace, I ALWAYS see several Prontos for sale here, what gives?
