Need 8 sheets to rebuild one on my place. Figure $500 or so. Hardware needed, guessing $100. New windows that will hopefully be water tight another $350. Total around $950 on an existing steel frame. Redneck with stand is around $3500. No doubt it is way better but sill another $2500 more than my calculation. Figure I'll rebuild it once and then in a few years replace it with a good one from Redneck or 360. Its a great spot and needs a comfortable place to spend a day on it.
