yup, window-shopping is a good way to go, to an extent...a PF40 or a TLE43 is a good start...now, drive-train & the actual chassis itself need looking at.
please...PLEASE...do yourself a favor: read read read! you still have a ton of work to do, and asking the age-old "what's the best?" will only get you so far. you have to know what you're buying, you shouldn't just ask us to "vote" for your parts. you say you wanna travel, so that's how i'm talkin' at ya.
for example, my engine & gearing decisions cost me mileage but gained me huge advantage in chassis strength & load capacity.
check out the review areas, read "the garage" & learn what's already been learned, about the pluses & minuses of different drive components, and about building a bicycle that's gonna rival a moped or light motorcycle in comfort, stability, and most importantly, safety.
and, buddy...i'll mention once & hope you heed well..."whichever's cheaper" is NOT a good policy when you start building the drive-train and chassis.
btw-i swear by golden eagle, as people and as product you can't get better than gebe. that's only my opinion, there are many here...have fun.
