What kind of trimmer are you looking for? something to take to crops? rotary? the best cut?
My top three are my genisis paper cutter (by bonnie's best-on facebook) but it is pricey!!!! But hands down the best cut in the business.
My second favorite is my cutterpillar. Very similar to genisis. Slightly more portable.
My Stampin' Up trimmer is great for crops, light weight and portable!!
