I think if you buy the Excaliber you wont have to worry about up-grade ing in a year or so.All the people that I know that have them,swear by
them,and never talk of switching to another brand,it may be a little
steep for you at this time but in the long run you will be money ahead
and and have the joy of working on your own equipment and being
independent of the shops to do all the little things that come up!As
much as I love my Parkers the shop has to change strings for me and
I have to carry an extra in case of an accident,good luck on your pick!
