Wow - Bill's Formula54 is an absolute steal at that price. You really should take him up on the offer. Quite honestly, you should consider paying him a bit extra to cover his shipping at the very least.
And anything that CJ (blackjack2564) offers would also be very worth your money. You will be getting some of the best built rockets you will find anywhere, and anything he has built/flown is sure to come with an extra bit of "mojo". He deals fair and square. Then, when you do start building your own, you'll know how to do it right.
Consider yourself very lucky for these offers, and If I were you, I'd move quickly on them.
Have a blast flying, s6
