you can make the caps your self. with aluminum sheets.  the problem is. whatever induction heater circuit i find. people find tons of problem with it. so i thought . why not? and i think if you look for it you can find some solution for effectiveness

and of course maybe if you add one or two more isolation transformer in between to change the voltage and amperage to desired level . it can make things better.

I am assuming you found these two webpages?
http://www.loneoceans.com/lo_main/labs_01/inductionheating/index.htm
http://www.powerlabs.org/indheating.htm

Using a spark gap induction heater is going to be a lot more dangerous as you need to insulate the coil to a much higher voltage. Additionally, it's going to be a less efficient and have limited output power. High power high voltage transformers are relatively uncommon and high power spark gaps are a bit tricky to get right and can be expensive.

I would strongly suggest you start with the induction heater kit on ebay. They work well and people on the forum know a lot about them, there is already a 10 page thread about the kit. At $30 it is also going to be a lot cheaper than any other option. Also, unlike the spark gap approach, they use a lower voltage, so it's a significantly reduced electrocution hazard.

eehh?! there is page like that ?! I just thought it myself ... but well. you see man. i need strong one . and need to work with it. it may look dangerous. but if you pick the parts right. then it simply becomes more dangerous to you and less to device. then you can isolated whole thing and control it from safe distance .
but it's not like i just want this. if you have idea for high power induction forge. lets hear it brother .  :)

so in the end i should use the first circuit with some improvements cause it's hard for tesla coil to lock on resonance frequency. then what about capacitor bank value . i doubt it's the bigger the better . or is it ?
