You can get the Optima 6 lite from Tom's RC online for $44.93 if you sign up for an account. Shipping is $3 usually.This is about the same price as the full size 6 channel and it looks like they both have the same specs except for weight and volume. They have good service and prices on most Hitec stuff and I have bought several Rxs from them. They are also on Ebay as tti.
If you want a good price on an Aurora 9/7 channel system see A Main Hobbies online. $325 with free shipping after discount code: DPPMAR1125. Good to the end of April and you can get a free 7 channel Rx from Hitec too!

I think it is wishful thinking to expect a quality RX with TM from Hitec for $20-$30. Maybe Hobby King will steal the technology and do it eventually.
Have fun
