I have an old 2213 that has no holder for the media at all, it all sits in the canister. The noodles are on the bottom, then a firm blue pad, then substrat, then white pad (I use quilt batting or cut filter padding myself)
When I clean it, I toss the white stuff. Then I pour the substrat into a colander, just keep a finger on the blue pad to keep the noodles in the canister. I dunk the colander of substrat in a bucket of tank water, swish around as needed. Then I pour the substrat into another bowl and do the same for the noodles. I do have to pick one or two bits of the substrat off the blue pad, but otherwise they stay separated.
When I am disconnecting th filter from the tank, I drain the outlet line of water into a big bucket to give me the tank water I need for rinsing, I just toss out the water in the canister for it is pretty dirty. This also helps clear the output line of any buildups. With the input line full of water, the output line full of air, the unit will prime instantly when connected, connect outputs and open, then connect inputs and open.
I also have the 2222. The baskets are nice, but there are a lot more parts to these than the 2213. I just bought two used tanks and they came with Eheim filters, mostly 18 months old, of the 4 filters, 2 were missing parts. The lady who had this was a very particular person, so I doubt that she lost them, she didn't realize that there was a seal missing on one and a connector missing on the other, so each of these 2 units was having some or a lot of bypass. The Pro2 she had was only using the top 1/4 inch of the topmost filter pad. I don't have any receipt and so I've had to buy the parts myself, though Eheim was really nice and covered part of one part and part of the shipping also.
So, the mechanical engineer in me needs to remind you that more parts = more stuff to go wrong. The simplicity of the 2213 is really appealing. Especially when I saw the $67 including media that the fish store in Austin has it for.
I had the 2213 running on a 20high for awhile that was way, way overstocked, along with a HOB Whisper, and based on that I think it will be fine for your 29 gallon. The flow rate on the 2213 is comparable to the Fluval 303 I have on my 29 gallon and it does fine all by itself, with a gentle circulation all around the tank.
