good?
audio? differential? instrumentation? hi-bandwidth
high slew rate? high current output?
with only a 5 volt rail you might look at opamps that are rail to rail
some have rail to rail outputs
some have rail to rail inputs as well
(basically they have cmos outputs)
why not get a cmos opamp ...low power (good for battery operation)
AD8661, AD8662 and AD8664
OPA703, 2703, 4703, 704, 2704, 4704

best bet is to look at RS or Farnell online

How do you mean?
The peak of the input signal will be 5v? or that it's gonna be on ±5V rails? or just 0v and 5v rails?
What will the frequency of the input be? What does the output need to be.
Usually, it's best to use one of the configurations of the 741 op-amp.

I like the AD8000, but it is very high bandwidth. For low bandwidth, use an LF353, and it is dual as well.
You need to define a number of things. Gain. Load. Inverting or non-inverting.
And you need to be careful of layout. And be sure and bypass properly.

Check out a TCL274 or TLV272 opamps. Available from Digikey.com

I agree with the previous answers, but add one more suggestion - you may have triangular wave in spice. Check the waveform at the input.. Also check you have plus and minus supplies correct. You expect 5V p-p output if the input is 0.5V p-p.

Depending on the details a LM324 might be good for your purpose - its a very old op amp.
