Vignesh ... You've got to decide what fits your priorities.

There is, of course, one obvious course I haven't mentioned yet. You can occasionally find a fully functional and adequate logic analyzer on eBay.

Be careful ... they're not worth anything if they're not complete, and that means with manuals. I've had a TEKTRONIX 1240 which I bought as a used portable instrument for over $1k, about 12 years ago because I wanted a portable. However, I have never regretted the price because I got everything I needed with it. It had plenty of grabber clips, 7 pods/probe sets, at least enough ground straps for two per pod, manuals, HPIB adapter, ROM pack, RAM pack, etc.

If you watch eBay at all, you'll see plenty of the instruments with just a few channels, or a full set, as mine has, for about $100-$200, but you'll also see individual pods, sometimes with the lead sets and sometimes not, for about that same amount. A complete instrument is the only thing I'd buy, including manuals, unless you are absolutely certain you can get a copy of them elsewhere. Remember, once you've got the instrument, if you lack components, the sellers have you "by the short-and-curly," so to speak. Don't put yourself at that disadvantage.

If you get a complete instrument, it will probably cost between 300 and 400 U.S. dollars. That's a lot of money, but the instrument is very useful. Remember, though, you've got to leave yourself some budget for an oscilloscope, too.
