I was looking at the Radiosouth site and I noticed the pricing it quite significant. I can see for higher end radios and servo, because I guess this price is only a fraction of the cost of getting new stuff. Is there a point in sending in like a 4-channel non-computer radio, with 3 standard servos? Between the shipping costs to and from, plus the cost of new parts, plus the labor charge, I think it might be more expensive than just buying new.
