I would say buy them from whoever you can find that has them in stock. A lot of places have them on backorder. I am waiting for a set from Slee Off-Road but they told me it wouldn't be until the middle or end of May until they get them from Spidertrax. Most places sell them for $99 a pair (~$200 for a set of two). You can also look on eBay or someone on one of these forums might have a used set for sale.
