Are you sure your PJ can't do PAL? Most can.

Also, many players have built in PAL-NTSC converters, you could try switching to one. Look for "region free" players since you will have DVDs from two regions. Panasonic is notorious for NOT having built in PAL-NTSC converters, most others offer them even if they aren't listed in the standard spec sheets. The regions may be a bigger issue for you than the conversion, actually.

You could also still buy DVDs from the USA.
