I use my scopecam only for aiming, so camera shake from recoil isn't a concern.
I just found out that Be Adaptive http://www.beadaptive.com/
offers a scopecam/monitor similar to mine for $700...kinda pricey but worthwhile if it keeps you in the hunt.
Do you read my blog? It has stories to keep you entertained between my forum posts.
My next trip will be to Argentina for red stag in March 2013.
But hey, I live in Rio de Janeiro, where just going to the grocery store is an adventure!
