I've bought at all three. They all ship fast. Stocks vary so I keep three windows open, add what I want to the three shopping carts then order from who ever is cheapest or has everything I want. I usually get a cheap kit while I'm at it since I'm allready paying for shipping.
It's actually the 24pk "Estes Blast-off flight pack" that is in their (TRU) brick and mortar stores. They vary in price from $27.00 to $32.00
Michaels also carries the Blast-off flight pack at $48.00, but with the 50% off coupon, it's $24.00 or a buck a motor.
looks great actually... alittle off... i needed b42's and c67's and d123's and d125's and a83's but to tell ya the truth ive never had a problem with ejection times... i think i put my pheonix up with a d125 last time (my lord im a criminal... shoot me) and it was a perfect flight... i guess ill just get em down by the hobby shop...
