need sub for TS271 - quick response please!

[GreenEye]

I'm going to try and get parts for the Amber Boost (during my lunch hour, which is fast approaching) to breadboard this weekend.  Joe specifies a TS271 CMOS opamp.  He says other op amps work, but aren't as dynamic.

If I have to sub, what are some good substitutions?  The place I'm going (Circuit Specialists in Mesa, AZ) seems to only have opamps that have an "NTE" prefix (on their website).  I may find more when I get out there.

Time is of the essence!

Thanks!
