Is it a bad idea to register with a reseller?

[crossbone]

I've been trying to find a registrar that accepts money order but only one that does is a reseller. the fee seems to be pretty good but can someone tell me why I shouldn't go with a reseller? btw, I've never registered before so any advice on what to look for in their service?
thanks!

Ps: If anyone can recommend a good registrar that accepts money order, lemme know!
