I saw a kit of a very similar plane today at my somewhat LCH. I'm pretty sure it was this one: http://www.luft46.com/mrart/mr229.html
It was made by DML I think, and was 28 bucks if I remember correctly. The two are almost identical, but with a few key differences. I like the angled wing on that HE.
I don't know that I've ever seen a kit of a Heinkel p-1079b. It's awfully neat looking though, I wouldn't mind having one around. I might have to settle for the Ho 229 however. Keep looking, you never know when you might find exactly what you're looking for!
Good luck.
