I did notice the the original Goldberg Ultimate ARF price had gone up but has now gone back down since hobbico bought them.
I have been looking to get the GP Ultimate for a while so hopefully they do not discontinue them before I get a hold of one. It seems that the ARFs disappear from the market faster than the kits did. Sometimes it is as if they only do one production run and then discontinue them. The other issue is being in stock. Look at Sig. It seems like they have a hard time maintaining stock as they do not seem to get enough produced.
