Saddlebags

Sadly, it's time to move on from my beloved milk crate and expand my storage options. I have a '23 s model (not adventure so no storage) that I'd like to get saddlebags for. Would like something waterproof, enough for 2 nights of clothes and toiletries, and won't require any additional racking to mount. As much as I love my KLR, my plan is to get something with a little more "umph" in a couple years so something that transfers would be awesome.

That said, what are your thoughts/recs? Don't want to break the bank but am willing to "buy once, cry once" for the right gear.
