I am not advocating reselling these specific items...just that there might be a market for them (or something better) through your website.
I've bought Harbor Freight items many times, and while they certainly aren't heirloom-quality tools they have always exceeded my expectations for the price.
This is probably the most cheaply-made slide puller on the planet, but for as often as you should need to use it, perhaps it does the trick for $17:

Or this set of $8 pre-bent probing tools--great fun for the shadetree dentist, as well as the shadetree mechanic. I admit -- I've snapped off the tips of more than $8 worth of screwdrivers trying to bend them into the tool to remove the water pump seals:
