Hi Guys.. Looking to buy a home dryer now the damp & rainy days are closing in. I've noticed that vented dryers (one that requires an external wall or window to hang the hose out of) are considerably cheaper than condensing dryers.. My question is, if I can't externally vent the dryer can I still get away with a vented dryer if I buy one of those D.I.Y. condensing kits? I guess my question is are the condensing kits any good? Thanks.
