Welcome Stuart:
Contact 9's are a good match for you, and you won't quickly outgrow them.? At this time of year, I wouldn't be in a hurry because this is the slowest time of the year.
1. Check eBay.? Many of the skis there are actually often by someone with a connection to a ski store.? Just do the research ahead of time to know what fair prices are.? The fact that you've already settled on a reasonable ski makes that easier.? This is probably your best bet.
2. Around here (Washington DC area) many of the ski stores have a 'beginning of season in August' sale trying to kick start the coming ski season.? They are pushing the new skis and soft goods, but often have leftover inventory as well.
3. May not be available in your area, but there are often ski swaps where you can pick up used skis at really good prices.? Ours are usually run by local ski patrols as a fundraiser.? Doubt that you have many ski patrols groups where you are.
4.? THIS IS THE BEST.? Tell Ron or Gary or Midwif what you are looking for and let them do the searching.? All are awesome shoppers, and there may be a pair in their local ski shops.
5. Post something the Buy, Sell, Looking for section.
I also wouldn't discount the idea of waiting until your next ski trip, and buying the skis that you demo.? Most ski stores will unload their demo equipment late in the year pretty agressively (especially if you negotiate a bit).
