You can roll your own if your handy.
http://www.realcent.org/viewtopic.php?f=21&t=4741I'm happy with mine, it is very accurate, and just a little slower. rarely jams and only cost me about 100 bucks to build.
It's doesn't look as nice and you have to figure out a lot of stuff on your own, but if your handy it's an option.
The CC16 Coin mech comparitors are on ebay, mine is built for nickels but works well with pennies. get one with the mount, there is a guy on there selling them with the mount and in coin optics( I have mine hooked to a coin counter) for under $20. I can post a link if there is interest, I'm at work now and eBay is blocked.
I can also help with telling what wire is what on the comparitors and in coin optics.
The hoppers are on ebay also, again get one for nickels. they are under 30 bucks.
Is it a Ryedale? No, but it's 1/5th of the price.
