edosan A different subject but congrats on your recent shooting & tuning on your gun you inspire me . I did see Bob-O's failure on his compressor ( bummer ) every time I think about getting one something happens (failure ) , was thinking of the spark just because its cheap in price for right now . I just don't care for the price of these compressors for their failure rate . I'll get a shoebox this winter for my great white but at this moment I also want a better top end gun ( vulcan - Tiapan long - Ed gun - ?) in 22cal maybe slugs a little undecided so trying to save a little money in that regared . thanks for the reply Darell
