[WTB] Tarptent Notch or similar UL solo tent

Looking to buy a Tarptent Notch, Six Moon Designs Lunar Solo, or other similar Ultralight tent (~<28oz) Would prefer a tent that has already been seam-sealed either by the previous owner or by the company. Would be willing to consider DCF if it was a good price. Would also consider a 2 person tent. Preferably double walled. Thanks!
