Sometimes it's better to 'sole source' a product and it's accessories to avoid the hassle of 'shopping around'. Generally speaking you will pay more if you do this. Tech support can be invaluable on occasion. I've found you can ALWAYS get a better price AFTER you've built your whatever.
The sales, the 'what if's', the new really good sources are endless in hindsight! And now that you've 'learned' perhaps you don't need that 'technical' support as much as when you started. Tough call when and where to buy.
