You paid $17 for the genco including shipping, Sending it out for honing will cost you at least $20-25 so that is at least $37. And if you want it restored you'll either have to spend some hours with sandpaper or pay more. At the end you will still have a razor with significant and uneven hone wear.
This or
this are priced at $25, they are not cosmetically great, but they are listed as shave-ready. Don't know about the brands, but I trust that most sellers here test the razors before sending out (and you can always ask).
Then
this particular one is priced at $37 and looks in great cosmetic condition, going by brand names should be as good as Genco, but of course you can ask the seller.
The additional advantage of buying in the classifieds is that you can start using them in 3 days, as opposed to 2-3 weeks (coming to you, going to the person to hone it and then coming back to you). And there are many other great values there - if in doubt ask some of the senior members for recommendation, most will gladly help.
There isn't anything wrong purchasing on ebay, but over and over I see new members buy razors there that have serious issues or need a lot of work, when they could've picked a whole lot better razors, ready to shave. Of course there is every now and then the occasional excellent buy, but that's extremely rare. You must realize that a lot of the experienced members also go on ebay and unless something flies under the radar you will pay more than what they are willing to pay. If it's cost effective for you to restore a razor and hone it up yourself, it may make sense to shop on ebay, but if you are planning to hire somebody else to do it it's almost always better to just go for the finished product directly.
