Magellan maestro 4000, 4040, 4050 vs mio...

Question

hi any suggestion for a new gps. i used to have a magellan roadmate 700 until someone broke in my car and stole it. i really love magellan or im just being biased. anyway im just looking for a gps that doesnt have that much but like to be accurate. i saw a magellan maestro 4000 off buydig and was thinking of buying it. but im also considering mio's line. anyone can tell me differences on same lines. like difference between maestro 4000 to 4050? also the Mio seems good. also have anyone ever heard of the plenio vxa3000??? thanks
