Do I really need Desoldering for replacing resistors/caps?

To replace such as resistors or caps.  Do I really need to get desoldering gun?   I was thinking to replace some of resistors and caps on ARC LS7.  The cheapest I seen was Hakko desoldering FR300-05 for $265, not sure if it worth it to buy it and will only use it once for this LS7.
Thank you,

i don't know the age of the unit you're talking about but if it's older than 5 years it'll have lead solder, and now (certainly here in the UK) lead solder is a rarity, the lead-free stuff doesn't play so well with leaded, so if you did decide to do it, and the unit is of an age where it's leaded solder, best to remove as much of it as possible ... you'll still have a surface covering and thats ok, but mixing a blob of one with a blob of another is not so good

just my 2pennyworth, and my first post here having lurked for some time but only recently signed up

cheers guys
