I switched to the LCD camp over 6.5 years ago now, and like itlnstln, I never looked back. Fortunately I had a good bit of co-financing from my understanding parents, as back then a good 19" still cost an arm and a leg - 866€ in this case, and this already was down from 1000+. Yours truly probably is a little more sensitive to flicker than the average person, and a flicker-free monitor was a godsend. At my average viewing distances, a *VA / IPS panel was a must, too - TN feels like looking into a tunnel of sorts. (Aside from a panel swap in warranty, the monitor has held up rather well.)
An old rule of thumb is to get the best kind of monitor you can reasonably afford. It will usually last quite a while.
I would be wary in terms of cheapo monitors. About the worst-case combo you can encounter is TN panel + fixed backlight output + shoddy build / durability issues. You can never get really good contrast if the backlight is not adjustable, and gamma will usually be way off, too. If on a budget, I'd look for used high-quality Eizos or NECs, with a bit of luck they're not too worn-down (that mainly affects the CCFL backlight, which may turn rather yellowish over time, but it takes a lot of hours at high output for that to happen).
