Have any of you used an Extech Multimeter before? I'm thinking of getting this one: http://www.radioshack.com/product/index.jsp?productId=2104750&cp=2032058.2032235.2032305&parentPage=family However, I'm new to electronics and I am wondering if this multimeter is worth it and if it will last- like when I get into the more complicated stuff, does it have functions that I would probably need. Are there any other better ones that I could get for about the same price? Thanks, Joe
