Donald, aka. spiderman, aka. el cheapo. I was reading the archives and, did you change/switch over r134 not too long ago with a kit from K-mart? Since you live in Texas where the weather is probably equivalent to Florida (where I live), how is the cooling with R-134 vs. R12. I know a lot of people asked this question before but, I would like to hear your opinion. What happened to "el cheapo"? Just curious...
