[WTB] The Big 4. Tent, Quilt, Pad, Pack.

Looking to start backpacking after months of day hiking. Looking for the big four. I'm on a budget so I'm not looking to buy a $600 cuben fiber tent. But, looking to buy quality gear that is fairly light that has been used to save some cash. Let me know what you have.

Pad: Neo Air X-Lite Pack: MLD, SWD, Palante, or something equivalent. Tent: 3f UL, SMD Tent, MSR, and BA ULA. Bag: EE Quilt (any degree that will work 3 seasons), HG Burrow.

I have a budget of $500-600 for all four.
