nose if you bought MXR a few months ago then you will have more than doubled your money. You should be a happy chappy!
If ERO falls to closer to 50c, which i actually doubt, i would have to be mad not to buy more. Do the maths and make sure to include everything including the cash in hand and you'll see what i mean.
Even at 40c MXR is good value.
They're both good value. OK?
cheers
