Biggest con I see with the LBO is that unless you are dang short, you can't stand up in it (64 in). Plus, if you start adding onto it, you quickly leave the cheap category of shelters.
The OP has the exact question I have, with a preference for standup capability and a small foot print. The Luna 4 has my eye from bpwd as does the KIS 4 man tipi. The KIS is getting kinda big. It seems about 75- 80 sq ft is good for two and stove, if they know each other well. SL5 is also big, but hard to ignore the price. Add on a custom nest, 50 for a stove jack and a few hours of labor though too.
Good tips so far. I'll be interested to hear more.
