If your going to buy HF pannels why not just buy them from HF? Cost may be a little more but not much. Your looking at $220 with shipping on that auction.
That 45watt kit is on sale now again, I just got the HF sales e-mail.
$200 for the kit. You should get new perfect stuff and have some type of waruantee. HF shipping is not normally too bad, and you get a free gift (A $49.99 Value) but I did not look to see what was. Anyway I dought shipping would be more that $30 so you might as well it about the same price.
If you have a HF store nearby they normally will give you the online price, You might have to pay sales tax then but not the shipping.
I always check online for anything I specifically want before I make the 150 mile drive to the HF store. Sometimes the stores do not have an item at the same price as online, they do match the price though if you show it to them.
Awhile back I had a 15% off coupon for any one item, I got a $329 bandsaw on sale for like $270 and 15% off that and the bandsaw cost me about $210 though you may have sales tax on that. I should have bought 2 and put one on EBAY
