Used Electrical Web Sites

It's interesting to see all the sites that are popping up as resellers of used electrical. Circuit Breakers get a huge paid ad content on google, yahoo, and msn search. What has become so interesting is the people who do not have big inventory but sell out of the other companies. If you can get the customer then you can find the breakers and make the money. So more people are creating sites that have incredible web abilities but no actual inventories.
The other trend seems to be starting new web sites that have the same parent company but do not clearly say this. I think this is to get more organic search hits and to make themselves look more popular with the search engines through a linking strategy.
These are all neat ways of making money but if you're buying or selling used electrical the web site should not be the deciding factor for buying. Do they warranty there product? How long have they been in business? Do they have knowledgeable salesmen and and a good price?
All in all Buying used circuit breakers and starters is a tricky business but it doesn't have to be. Find out how long they've been in business and if they guarantee there work I think that it will be worth the effort.
