Is it worth it? DD is at the stage where we can sit her up against things. I was thinking about getting the bumbo to help with the sitting, but also getting a tray to help with beginning to feed her.
Do you love your bumbo? Was it worth the $38, or even the $20 I can find it on craigslist for? 
Re: Bumbo?
We bought a bumbo a few weeks ago and DD loves it. She was desperately wanting to sit up and got annoyed with not being able to sit up all the time. The Bumbo lets her sit up and look around, which is exactly what she wants right now.
The Bumbo is nice in that it is light and easy to move--you can even kick it along the floor to move it (obviously while it is empty and you are holding the baby). It also doesn't hurt when you trip over it.
This is a great idea! Fellow Nesties, does anyone have a bumbo I may borrow?
I should point out that we don't have a high chair either, so it's a toss up between purchasing a bumbo and a highchair, or just using the funds towards a highchair and new shoes for mama
ETA: We have the tray too and we use it as a high chair when we go OOT.

the tray spins and hold snacks. you can take it off, it has optional feet for stability and it straps to the chair for a highchair/booster

Blue or Pink? We have both! You're welcome to borrow/use until no longer needed. We have a tray. I only need it back eventually because I promised a friend she could have all my stuff when she has a baby (they're officially starting to try this month)
Emily was already a little too old for it when we finally got one and then too mobile to tolerate it for long.
