Replying to Touring inserts for alpine bindings

So I've been looking into doing a little touring around the Whistler area ( yes I know, avy courses) but I really don"t want to take my alpine bindings off my bent chetlers or buy a whole new set up. I'm just looking for something that is cheap and will work for 1 or 2 days a season. I found these ( [1] http://www.backcountryaccess.com/product/trekker/ ) online and was looking for any advice on either these or how to get into touring. Also are there any other brands out there? $180 is a little pricey but I haven't been able to find anything else like these. On a little side note, is there a reputable and standard avy course to take? Comparable to what St. Johns Ambulance is to first aid? Thanks in advance for any help!
