I had a blow-out on my 5'er which broke the skirt as well. When I get ready to replace it I'm getting mine off Amazon.com. Already researched and found that it is the cheapest way to go. Like said above, 10 minutes with a screwdriver and a little sealant sure will save $50. JMHO.
Jimkuy, this restocking fee is a new way for business to make more money, been there, went through it. Maybe you can cut your losses and resell the wrong one as they are always the first thing to take a hit when one has a blow-out. Good luck with your decision and I feel your frustration with those awful restocking fees!
