In regards to KVR you will find a lot of the sellers are legit, ask a question and check out with one of the mods on the webby. KVR is a pretty wholsesome site in general.

However, I would recommend Zebra2.5. ADvertised at $200 but send in a photo of an old keyboard and you get a $50 dollar off voucher.
Obviously make sure the photo looks like you own the kit.
Zebra is much better value, widely respected and supported imho vs Ultra VA-1.
