I am a reseller, so no: I don't bother me.
There's a place for resellers in a community, I believe... but there are good resellers and bad resellers.
In my business I mostly deal in Sinclair Spectrums, though I do a bit of Amiga stuff, and yes, I trawl eBay for bargains, and yes, that does unfortunately stop other people getting a bargain. But my highest bid is nearly always notably under the average - I place a lot of bids, but I don't win many.
But on the other hand, I
do offer a service.
Some (many!) of the lots I win are only partially working. By the time they leave my office (at a definite mark-up) they're fully working, refurbished (cosmetically and more importantly electronically), tested and guaranteed. Without resellers like myself it would be impossible to buy tested, working guaranteed old computers on eBay... and it's not like there's not a ton of untested ones on there still. Sometimes I do just buy something in cheap and then sell it at three times the price - but when I buy it it's almost always untested and when the buyer pays me, he knows it'll work.
As a reseller, I'm not just selling goods - I'm selling my knowledge and ability to repair, test and refurbish 30-year old machinery.
A good reseller provides a service and allows the continuation of the hobby. A bad reseller buys cheap and chucks it out the door at a massive mark-up.
So I hope I don't bother too many people. My customers don't seem to think so, anyway.
