I'd say that if you haven't tried it yet, by all means give it a shot. You'll get some experience, learn about a hot topic of research, be around people you can ask questions about it, and hopefully, find a place you'll fit in and feel comfortable. I've supervised a few research assistantships that proved very valuable to the participants, whether the jobs ended up in their getting more involved or in their ultimately realizing research was not for them.
My opinion is that it will only add to your knowledge and skill set, but only *you* can decide whether it would be more valuable to you than what you'd do otherwise. For example, if you'd be taking more summer courses otherwise and you feel behind the curve in your studies, maybe doing that would end up being more helpful to you, but if you'd planned to get a full-time job at the local donut shop otherwise, then I'd definitely pick the research.
Not everyone gets the opportunity to do research as an undergrad, so generally I'd say go for it, especially if the group seems like a friendly and positive bunch of people (if other students working there seem unhappy, of course, I'd avoid working with that group).
I've done lots of research myself, so feel free to PM me with (or ask here!) any other specific questions you may have. Good luck!
