I know the FAQ says to just search ebay, but is there anything I should be looking for in such a lock? obviously there are a lot of different unbranded options on ebay and I wouldn't want to buy something trashy. I know sparrows sells some as well, are there any actual brands anyone would want to recommend or is it not worth the extra $? Also, I've noticed many (sparrows, for instance) use a schlage keyway- I've heard many that advise avoiding this as a beginner as the warding is more difficult. should I be looking for a kwikset keyway instead?
here is sparrow's page: http://www.sparrowslockpicks.com/category_s/85.htm
and here is one lock I was looking at on ebay: http://www.ebay.com/itm/7-Pin-Pin-Your- ... Sw41xXO2Et
also, lots consisting of no-name 2 pin, 3 pin, 4 pin, etc locks seem to be abundant in the search results of "practice lock" on ebay. would it be more economical to go with these? I understand that I couldn't pin for different bitting or throw in some security pins as I progress, which seems like it would kind of defeat the point of going out of my way/spending extra $ for a practice lock...
