Prety sure that Weller is just a semi-fancy base with a $16 iron. The TrakPower is either a re-badged Hakko 936 or a really good chinese knockoff of a Hakko 936. I have a Hakko 936, and it's wayyy better than that weller. The weller gets just as hot, but's it's just more crude than the Hakko. The cord for the handle on the Hakko is a lot more flexible which makes a lot of difference IMO.
