If you are going propane get a Coleman Northstar they are super bright. You might find it at Walmart run about $60. I've got two they are awesome. Propane lanterns are hard to beat unless you are going to be up high.

Coleman does sell a two mantle dual fuel lantern. I've got an old single mantle dual fuel lantern which has never been used. Its a SHFT lantern but I have enough propane stored to last several weeks.
