If spend abt $120 for dry cabinet and a $25 for dry box... I dunno how long it can last for a bottle of gel but I bought it at $3.50 (I assume it can last for 1yr and some might wan to re-use by re-heating in the microwave?). As 1 of u said it uses $5 of electricity per year... in long run, probably 5-years since cabinet warranty for 5yrs only (am I rite?)...
Cost after 5years:
Dry cabinet: $120 + $5*5 = $145, U spend 145/5 = $29.00/yr
Dry box: $25 + $3.50*5 = $42.50, U spend 42.50/5 = $8.50/yr
If people try re-heating it, probably nid 1 bottle throughout the 5yrs? I tried re-heating but it seems to hv no effect. (Anybody can teach me on this? :dunno
But the con of using dry box is the nid to change of silica gel and the hydrometer might not be as accurate as cabinet. And definitely cabinet looks better... hahaha
