Where have all the good men gone is not the question. The question is; where can you get a good one? Well, just as the old maxim decrees “If you want it done right, you have to do it your self.” Build one at home just like these girls are doing. It very well may be the only sensible way to go and if it doesn’t work out, well, who is going to miss a frog or two? Good luck!
