[The Jester of Wibbly]

George all the way.  For £50 cant go wrong.  Easy to maintain and easy to use, simple to understand.  And does the job intended.  I have used it for 7 years with no issues.

Only down side is you have to print out your worksheet rather than have an electronic cloud copy.  Although you can buy an outdated palm for it on ebay as a workaround to go paperless.   But for me that option is much better than paying over £1200 (based on a seven year subscription).  Means I can afford an extra holiday for the family
