I do recommend the manual ones over the digital. The digital one I got went funky after a year and half. Never had issues with the manual ones.
Actually the first one I got was at a rummage sale for $12. that thing ran over seven years! So they don't seem to wear out. If you go to Lowe's you can get an extended replacement warranty....I think it's for three years so defiantly get it if you go digital.
Thank you. :)
