Thank you all. Yes, SWIM plans to try it but lack of a proper place to do so makes it kind of hard. Some "sources" can be trusted and their knowledge is far greater than anything someone can pick up from a tek. But, price and availability issues would be solved by trying these methods. I have been reading a lot of information and it seems possible. The first tek I ever saw was something far too advanced to even try. Some of the ones linked to here may be a better route. I just wish I could watch someone do it in person so I could feel more comfortable. Oh well. Trial and error will have to suffice.
