Ive used DMS and MK Racing - both excellent service and no problems.
Some folk arent as proficient at scouring the net for parts as others. I for one arent offended at DMS or anyone else offering up what they have available when the specific question is asked.
I cant see why anyone else would be either ?
If i was paying my mortgage from sales of RC gear then id be doing my best to tell folk how good my service was too
Just my 2p
