I have played much more than 1000 hands of no-limit. I just feel that it is easier to make a consistent profit playing limit. When playing no-limit, the importance of being able to put a player on a hand goes way up. I find that very hard to do with so many “any two cards can win” types playing online. Perhaps I need to work on my no-limit cash game skills, but for now I am content to turn a regular profit playing limit.
I'd just recommend playing the $25 max buyin NL 6 max games at party.The buyin is for .25/.5 normally it's $50 but party has half max buyins so if you lose a buyin you're not losing a fortune. I think a fine guideline is to have 7x-10x the buyin (of standard maximum buyins) so $500 for the $25 at party. That said back when I played those stakes I was only on $200 but even then I was an educated player.I play NL, PL and limit, mostly the former two. Yes, there are swings, but there are swings in fixed too so, as long as you're within bankroll guidelines and of sound mind you should learn how to cope with it. Beware though, if you genuinely can't find enough courage / heart to play No Limit you should just stick to fixed. Try to play at least a thousand hands before you let NL scare you off. Also, find a reason for it being "scary" and try to solve it.
It is too early in my online poker career to say whether I win consistently or not, but in 4 months, I have built up my bank role (from $50) enough to play 5-10. Personally, I would avoid no-limit cash games unless you have a huge bank role to absorb the large swings. (And the mental toughness.) If you must play no-limit, start with the $5 SNGs. That is how I started.
