look at the 'gear' part.. the 2nd deck looks like TB EVO3.. and closed bulkhead design..
where is the PRO4 now? er...

Its easier to give you a list based on what budget you have in mind! The CE pitbull would be a good start at a little over $1000, but you also need a power supply.

What makes these chargers so expensive. It is just a voltage controlled current source.

I heard that there is a RC track in Shun Tak Center. Is it true?

Xray T1R
How much is the Xray T1R??

If you have the knowhow, you can built your own simple charger with a simple timer and it will work fine.
Another factor is simply supply and demand.

These type of charger come out in the old days while microcontroller are expensive, so the initial price is high and the price fixed at that range, like audio CD, they are extremely cheap to produce.

In old days, when we are using NiCd, there are many tricks like neg-pulse [Tekin PowerFlex], and cycling. However, the NiMH now doesn't like all those trick, they just like simple linear charging. Most important is to have a correct cut-off point.
Seems the charger doesn't need to have all those trick and even an APEX charger can have a good result!

For long term investment, you can try the PitBull [around 11xx]
or you can find some old 2nd hand Tekin BC112A with firmware later than H26 for 4xx [a classic good charger, but Tekin is closed now so can not offer after sales service anymore]

So for pitbull, I need to buy power supply too.
Where to buy 2nd hand stuff??

i think you may stay with the TLP charger for a while and get a better one when you skill has improved.

I also dropped the car on the floor one day, damaged the rear shock tower, fixed it with CA glue. The car is still in excellent condition.
Getting better now, still need to get used to the setup of the car.
