I have the WESD51 (digital controlled version of WES51 linked above). The WESD51 is also a good sub $100 iron.
The WE1010 looks interesting - must be a new model of theirs.
The WE1010 is a 70W iron versus the 50W used by WES51/WESD51.
The 70W will hold heat better than the 50W but will take a bit longer to heat up.
All three use the same tips.
Overall - the WE1010 looks to be a good choice and a bit better than the WESD51.
