Why don't you help the members help you? What are your needs? What are your limitations?
Max sine frequency
Max square wave frequency
Arbitrary waveform required - how many points, how high the frequency
How many channels
What voltage levels versus frequency (ok, this may be over the top but it does separate Siglent from Rigol in the higher end models)
What do you plan to use it for (at least for now, things will change in the future).
Can you get by with a truly cheap signal generator (FG085 $50 -
https://www.sparkfun.com/products/11394). A neat little unit but hardly high end (I have one)
Is a USB model (PC controlled) acceptable?
Have you searched the forum for other discussions. There are some epic threads but typically for tools that are a little more expensive. You may find stuff in the $50 range and stuff up over $250, I'm not sure what is available in the middle. If I were buying an Arbitrary Wavefore Generator right now, it would be the Siglent DSG2042X.
OTOH, if the specs would meet my needs, I would buy the Digilent Analog Discovery for $279 and be happy with all the features:

Do a little more homework and state your requirements.
FWIW, I do not have a bench Arbitrary Waveform Generator. I might buy one but I'm still trying to figure out why. I've been doing this stuff a long time and in my corner of the electronics sand box, it just hasn't been necessary. Especially since I have two other ways of generating something.
