400 is bit expensive, i will see if i can get a used, is it really a huge difference in the gen strap?
there are 4 types of strap from what i know.
1 = plain rubber
2 = vulcanized rubber strap
3 = croc strap
4 = rubber + croc strap
1) the plain rubber has very different quality between rep and gen (must buy). really soft and comfortable, not stiff.
2) the vulcanized rubber strap is the closest between rep and gen. but the gen is more elastic and it doesnt hurt your arm.
3) the croc strap quality is better on the gen
4) havent compare between gen and rep yet. but i believe the gen is slightly better quality.
the buckle on the gen is better. if you want a true comfortable watch, buy the gen strap and buckle. but thats expensive. choice is yours =)
take care
