Before you part with your hard earned money, do yourself a huge favor and check for the product reliability, company attitude and customer service of the company you will be dealing with.
Recently we have seen several very interesting post on here from folks that were being screwed royally by vendors who advertised their products on this forum. 98% of the vendors are very up front and will bend over backwards to have a satisfied customer, but there is always that 2% and they have been front and center lately.
A simple search of the company and or the product will bring the problems to the top.
