I was thinking of getting the setup linked to below, the Smith VT-4T . It seems as good as any other kit and it contains the AW1A torch which most people seem to recommend for frame building (I think that I can use the small tanks and cutting torch for other things, also.)

However, I'm not sure if its just the picture, but the regulators look sort of dinky compared to what I'm used to using. Does it make any difference in terms of functionality or safety?
Also, I read on another forum that the welding tip with screw on nozzles that comes with it isn't really very good and was was wondering if someone would recommend an alternative tip/tips, sized for frame brazing. The chart below gives some of the available smith sizes.



I also would like to get recommendations for flux and bronze. At this point I will just be practicing brazing, so I'd like to buy flux and bronze that could be used to build a frame but with the emphasis on economy.

If anyone has any suggestions or advice on what else I might need, I would be glad to hear it. I know from reading the forums that many people have suggested buying things piecemeal, but I'd prefer to avoid any possible incompatibilites, worn equipment and daily ebay searches and to just get to the brazing.
