Is there a desoldering tool around $50 thats alot better than using wick or cheap $5 hand pump ? I have some components that are soldered on the top and bottom of the pcb and I just can't seem to get all the solder out .

For difficult to desolder things, cut the component off, grab the remaining lead with needle nose pliers, add some solder to the joint, heat the joint with your iron, pull out the lead with the pliers, this will likely leave the hole full of solder, heat one side of the hole with the iron and use the solder sucker at the same time on the other side to clean out the hole (this may require help from another person).
In my experience, having used the RS one shown, it isn't good, or effective at removing a lot of stuff.
At 45 watts, you could do damage to boards with that puppy if you leave it on too long.
One tip, so if you have to pull a smaller component, well, good luck.
Here is the bottom line: you get what you pay for. If you can't afford a good de-soldering tool, either save up until you can, or try to pick up a good tool on the used market.
So, what is wrong with the RS Tool:
1. 2 hand operation. You have to hold the iron in position to heat the part, and then squeeze the bulb with the other hand while holding it in position, to pull the solder. A good, dedicated de-solderer has a pump, which you can quickly engage to pull out the solder. One hand means you can hold the board, or pull the component.
2. Since both hands are busy, you can't pull the heated component out when you have the solder liquified, to help clear the hole. That means having friends help you. (Possible, but now you need to coordinate efforts).
3. RS product. Enough said?
I've tried them - they just aren't good enough for real work. They are good for the hobby guy, working on RS projects, and for very light work.
Skip to 1:27 in the video above to get to the part I was talking about.
Yep, that's how long it takes.
45 watts is pretty high power.
Yes, you can do it with one hand. You don't get full compression. If you want to really get a good pull, you compress the bulb more with both hands.
I still think you'd be better off saving up, and getting a better tool. I've done it both ways, and I'll never go back to the squeeze bulb / spring suckers.

I've used the RS one for years without any major issue. I have chewed up a board or two though. I think that has been because of the angle that I've had to hold it. It is a bit culmsy.
I currently use this one that happ sells: http://na.suzohapp.com/tools/92075900.htm.
It works great and I've had no issues at all so far.
$45? yikes
