ive recieved parts for my tamiya tl-01 from rcmart using the fastest shipping method it was her in 3 days excellent service, star guitar and nearly evry1 on this forum wit savages has ordered them from towerhobies, to me rcxshop is a ripoff
Everyone I know (myself included) purchased their Savages from Tower hobbies. I have also had subsequent orders from them and they provide quite reasonable delivery and offer afair return policy.
I also have purchased RC gear off MRC model car parts (one of our partnersat the top) andMark has been very competitive with overseas stores on price, and his delivery times are fantastic. (especially compared to overseas deliveries)
I recently had a problem with a part I purchased from MRCmcp and getting a replacement was as easy as sending an email. Mark also sells Savages, and if I had known of his store prior to purchasing my Savage, I might have had it in less than a week rather than three.
I've had no experience with the other stores you mentioned.
