CO2 fill for kegs in Boulder?

Can anyone recommend a place to get a CO2 tank filled in Boulder? I've discovered that "Hop To It" will do an exchange or they will fill my own tank, but it will take a few days (they send it to their shop in Denver).
I'd rather keep my tank and not have it take a few days. Any suggestions?
Thanks.

CO2 fills
I just did a survey of the surrounding area regarding this. Many people just go with the refill, it's quick, easy, with instant turn around. If I lived closer to that Red Comet, I'd probably be getting refills there. Hop to It's bottles are fine, we've got 2, although it's a tiny bit disconcerting that the valve handles have a backwards S in CLOSE. Also of note that if you can get a bigger bottle it's a lot more economical. If you have any more info please feel free to share it here.
Here's what I figured out with help from the HBA mailing list:
Out of eight responses I only got one that was actually refilling
their bottle vs exchanging it. The primary issue with refill is extra
cost for hydrostatic testing and re-certification every 5? years.
Internet research says to check gas supply shops, aquarium, fire
extinguisher, welding, liquor stores, and homebrew stores.
These are the places I'm aware of:
General Air - $17 - exchange
AirGas - $17.50 - exchange
Hop To It - $15 - exchange
Total Beverage (Westminster) - $14 - exchange
Wagner Welding (Longmont) - $14.45 - mostly exchange, but they will
fill if you leave tank with them
Denver Syrup & Bar Supply off 56th & I25 - $8 - refill -
$20(recertification + fill) Said they fill between 8am-10am
Red Comet ADX (http://www.redcomet-adx.com/)
We fill CO2 bottles while you wait providing your bottle is up to
current test date.
Pricing on CO2 Fills:
* 2.5lb = $7.00
* 5.0lb = $8.00
* 10lb = $9.50
* 15lb = $10.50
* 20lb = $12.00
* 50lb = $40.00
Hydro testing is $14.75 on 2.5lb-20lb bottles
Re: CO2 fills
Thanks for the reply. A few comments...
"The primary issue with refill is extra cost for hydrostatic testing and re-certification every 5? years."
It seems to me that "Refillers" can avoid this problem by exchanging their tank once at some point before the 5 year limit. Agreed?
Also... to add to your list. I just got my 5lb tank filled at:
John's 4X4 Center Inc
www.johns4x4.com
6367 Arapahoe Road
Boulder, CO 80303
(303) 449-2640
Hours: Monday through Friday from 7:30 a.m. to 5:30 p.m.
The cost was $14 and some coins. They filled my tank more-or-less immediately. They told me they get a lot of business from those wishing to push beer around with C02.
So, I think I will refill there for a few years and then exchange sometime before the date on my bottle. Does this seem like a reasonable plan?
Thanks.
