If you sell it you always could buy another one down the road. That's what I did. Money got tight so I sold the 2002 that I bought new and built up. I took a few years off and when money was good again I bought my 2004. Family is more important, do what you gotta do man.
Hopefully this ride can help you out but this really needs to be pulled together if it's going to produce any money. We need WAY more donations. I don't think 6 items is near enough to do a silent auction. At the benefit that we did for my Wife's Uncle we had like 300 different items. Some items were small $5 items like a haircut to a full blown 10 day vacation in the Caribbean. With that being said, you don't have to stick to quad related items only. Gift cards to restaurants, hand made items (like if you know someone who can make some corn hole boards and bags) and anything else that you can get donated really. It'll all get bids. Your main goal would be to sell the raffle tickets so the better your items the more tickets you'll sell. Companies generally are glad to help out, What we found is the majority of companies we called had a monthly allowance for donations which a lot of times go un-donated. Donations bring the company future business as well as a tax break.
