Shaun, that is a nice finished product!
I too ordered from Ryan via ebay back in december. the cabinet came with a few damaged pieces that Ryan was quick to either replace or cover with a free vinyl kit. I chose the replacement parts as one of the pieces looked a little too damaged to salvage. he was also quick to answer a few other questions as well.
overall i am happy with the product.
I would say that there is some minor quality control issues with the kit, a chip here a chip there, but overall it is very nice. I have no frame of reference to compare him to other vendors (looks like Haruman is the only other option?) but i would say that the kit was well put together and is also the only comprehensive kit i have seen with button options, controllers, etc and even tutorials on the site. is there room for improvement? sure, based on my quick search there isn't a lot of other options out there.
I will probably order a Haruman kit as well as i want a 1 player vertical cabinet and Ryan does not offer them.
all that said....would i order from Ryan again? probably. based on the stories i have heard here, i would probably do it via ebay again, as it provides additional protection. I would also recommend a vinyl kit as having that would more or less eliminate any quality issue i have seen in the product.
