Where are you located in MI? There are several of us from MI on the forum who may be able to get you pointed to someplace local.
We did a season lease for my son this year. It has worked out well and I don't regret it, but there are some pluses and minuses. On the plus side, he got brand new skis, bindings and boots that actually fit him. If we were to purchase the same equipment new, it would have cost about $400 ($250 skis, $150 boots). The lease cost $169. He'll ski about 25 days this year so the cost averages out to less than $7 per day...not bad at all. The only downside is we return the equipment in April and get nothing back.
For my 9yo daughter, I watched Craigslist and Ebay and was able to get her some used (2009), but in like new condition Dynastar skis with bindings, boots and poles for $60. The boots were a size too big and I sold them for $20 and ended up buying her a different pair that fit much better from Craigslist for $30. So in total it cost me $70 for her and I'm pretty confident I'll be able to sell them next season for at least that amount and then get her new used equipment again.
Neither of my kids race so I just don't see the need to buy them high-end equipment when they'll outgrow it each year. My son took his very first lesson on these skis this year and he skis them parallel on most slopes now so I can honestly say his equipment hasn't held him back one bit. We may lease again next year or I may try to do the same thing for my son that I did for my daughter. If I buy used, my goal will be to find relatively new equipment (5 years old or newer) in good condition that I can resell without a problem when they outgrow it. They both may get new boots though as finding used boots that actually fit off of CL or Ebay can be a pain.
I may be a bad dad, but in my mind kids skis are kids skis, especially for anything we ski here in Michigan. Find a decent ski in the correct length and let them have at it. They won't know the difference between what was a new $200 ski and a $500 ski. Heck my daughter is more concerned about the look of her skis than anything else. Here's a size chart that may help choose the correct length. Just keep in mind you're buying for next year and they will grow between now and then.
