If you can give up on-screen approach charts, a handheld GPS with an SL30 nav/com is the way to go. The 296/396/496's are actually better GPS's than the 430, and you can take it home with you to program your trip. The difference in price would pay for about 5 years worth of weather subscription. By the way, the map subscription required to actually use a 430 as an IFR GPS costs about a grand a year, last time I checked.
Personally, I'd rather have weather in the cockpit than a controller in my ear.
