Best reasonable aerating system?

Sub $60

Not really trying to get anything that would require o2 tank

I use this system: http://www.northernbrewer.com/shop/brewing/brewing-equipment/fermenting-equipment/aeration-system.html

It works well. It's inexpensive. It's easy.

I use a Venturi device made by mazzei. When I get off my phone I can get a better link. Works great IMO, and it's under 30 bucks. I've never measured my O2 content, and have only done 5 batches but all have gone off without a hitch.

I use a (sanitized) strainer to filter out hops/break from my cooled wort when transferring to primary fermenter. Then pitch the yeast and give it vigorous mix with my (sanitized) spoon. Cost = free!
The straining seems to aerate well enough - active fermentation begins within hours and I achieve expected attenuation every time...

I see to always hit my final gravities, but I still have a somewhat sweet and thick flavor to the beer afterwards. I think this is due to not enough oxygen in the wort. I'll be buying an oxygen setup before my next batch.

I use William's Oxygen Aeration Kit

Disposable tanks are like 8 bucks at any hardware store.

Without using pure O2 you're limited to 8ppm of O2 MAX. Nothing you can do will ever give you more without using pure O2. Just a fact of physics. If you want more, you have to go to a pure O2 system.

I have a couple of the William's wands, which work really great. You can also use the same regulator with a length of tubing and connect up an air stone (either 2 micron or .5 micron) and oxygenate that way. You won't have the same level of placement control you get from the Williams wand, but if you're more concerned over cost, that would be far better than any method NOT using pure O2.

I plan on trying to silver solder a swivel nut onto the end of a length of stainless tubing soon. That will allow me to change the air stone (ones with 1/4" MFL connections at least) and use whichever size hole I wish. I want to test to see which is better, the .5 micron or 2 micron. Or if there's no difference at our scale. I'll probably get an O2 meter for this too and brew a couple of batches with either the same OG, or as close as I can.

A little frustrated with same-O-same?
OP:
The cheapest way out is a disposable oxy tank from almost any hardware. If you are a diy welder, use your welding oxy through a hepa filter.

No hepa filter needed with pure O2... You need one if you're using an aquarium pump, or other atmospheric O2 source though.

You can also score some O2 regulators from ebray or Amazon for under $40 each with the standard welding tank connection, CGA 540. You'll get a TON of batches out of the smallest O2 tank you can get from a welding supply shop.
