Intercom question

Hi All,
I have been lurking here for some time now and enjoy some of the very
interesting threads that take place.
Jay always seems to come up with something interesting.
Now I have a question and I hope some of you experienced people don't mind
wading in.
I own a Piper ArcherII PA28-181.
In all the years I have flown this aircraft I haven't used a headset, mainly
because when I have tried it I find it strange not hearing the same engine
sound I have always been used to.
Due to some peer pressure, and mates that fly with me making the suggestion
an intercom would be great, I have now started to think about it.
Not having had any real experience with intercoms, I am wondering what your
thoughts are on the Telex PC4 unit. I have seen one advertised second hand
and because I'm not sure if I will like the thing, I'm thinking a low budget
might be a good idea.
Any thoughts, experiences would be appreciated.

Kind regards
Steve.
