Considering the Yammy ef2600 sells in the $800-1K range and the conversion runs $100ish on sale. Not including the regulator and hose. It's a good deal. DEPENDING on S&H cost

Personally i'd go with the EF1000. Better bang for the buck, considering the 2600 is bulky and really doesn't run much. The EF1K will power the frige and all your camping gear
