Definitely. I had a similar hiatus and found lots of differences -for starters,
glass aquaria have become wonderfully cheap.

Well, not everybody, just a certain category of plant nuts.

A good system should cost you more like $200 including the CO2 cylinder.

If you want to "dip your feet in" like this, there are a couple of better ways:
Bioplast makes a "CO2 System" that uses alka-seltzer-like tablets to add CO2.
Second, go to a bicycle shop and buy a $20 gadget for inflating tires using
CO2, or the near-identical gadget sold at office supply stores for dusting
equipment. They both use tiny CO2 cylinders like a BB gun uses. Invert a
water-filled jar inside the tank and fill the jar with CO2 once a day.

I'm not sure just how much CO2 you'd be adding with soda water, but it would be
sudden. Both of the methods I mentioned above use a bell device to store and
gradually dissolve the CO2 so they're safer.
Both also don't work half as well as a real CO2 cylinder. I have setups on two
tanks that cost about $150 each, and work for about 6 months between $15
refills. Can't beat that.

Especially not with a twist of lemon. :)
