I believe there's a perfect instrument for everyone who wants to play one, but there's nothing to stop you trying out the not so perfect ones as well.
I took up guitar and was able to knock out a recognisable tune or two after a few months, but it really wasn't 'me' so I never bothered much after that. How easy (or not) it is to pick up is a very individual thing, depending on the style you want to play, your physical make-up and your intellectual strengths (you need reasonable ambidexterity and sense of rhythm to play a guitar well).
If it's something you really want to do, go for it. There are some good quality, inexpensive guitars out there that are perfectly suitable for beginners. If you decide you like it, then you can upgrade to something else. If not, well, you haven't lost much.
